When your exam gets closer, live in this section. It focuses on the things that actually move your grade: formulas, required practicals, and past papers.
Tip: every time you finish a topic, do 3–5 past-paper questions from that topic and mark them with the mark scheme.
How to Use This Site
1. Pick your weakest topic from the list above.
2. Read the short notes and check the key formulas.
3. Work through the examples and do the quick questions without looking at the answers.
4. Finally, go to the Exam Tools section and do real past-paper questions.
You don't have to be “good at physics”. You just need to keep fixing one small topic at a time.
